SHIP FOR CARRYING LIVE LOBSTERS AND THE LIKE.

Specification of Letters Patent.

1 Patented Jan. '7, 1919.

Application filed March 19, 1918. Serial No. 223,349.

To all whom it may concern: r Be it known that I, J osnrrr E. Woos'rnn, a

mont, in the county of Hancockand State ofMaine, have invented certain new and useful Improvements in Ships for Carrying Live Lobsters and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to commercial boats and the primary object of the invention is the provision 0 an improved boat forcarrying live lobsters and the like to market so that the same will be kept in alive and fresh condition. v

Another object of the invention is the provision of an improved boat for carrying live lobsters and the like in which the ordinary method of havinga compartment of a vessel in direct communication with the water at all times is dispensed with anda water tight compartment or well substituted therefor for receiving the lobsters, in which water can be introduced and drained therefrom at the pleasure of the master of the vessel. 1

A further object of the inventionis the provision of an improved lobster smack for carrying lobsters and the like having a central water tight compartment with valves for letting water into the same, and a pump to keep a circulation of water through the compartment and for draining the same, when so desired so that the vessel can run under a light load.

A. still further object of the invention is the provision of a vessel of the above character, which is durable and eflicient in use, one that is simple and easy to construct, and one that can be placed upon the market at a reasonable cost.

A still further object of the invention is a provision for the reversing of the positions of the suction and discharge ipes of the pump, in said boat, so as to fill t e compartment to a point about sea level, or waterline of boat when so desired.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings forming a part thereof, in which:

Figure 1 is a side elevation. of the improved vessel constructed in accordance with my invention.

Fig. 2 is a central longitudinal section takenthrough the improved vessel.

Fig. 3 is a horizontal longitudinal section taken through the improved vessel.

Fig. 4 is a transverse view taken on the line H of Fig. 1.

Fig. 5 is a detail perspective view of one of the crates for receiving the lobster.

Fig. 6 is a detail view through the sea valve taken 011 the line 6-6 of Fig. 4.

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 1 generally indicates the improved vessel, which can be of the ordinary or any preferred form, and which hasspaced partitions or bulkheads 2 extending transversely thereof defining a central compartment 3. The bulkheads extend downwardly from the deck 4; of the vessel to the bottom 5 and from one side wall 6. to the opposite side wall 6 and the woutwardly into the water and communicate with the compartment 3 and the same allow the entrance of water into the compartment. A valve 8 is threadedly connected as at 9 to each pipe 7 for controllin the flow of water into the compartment. uitable operating rods 10 extend upwardly from the valves to the deck and each of the same are provided with a hand wheel 11, so that the valves can be readily turned. Thus, it can be seen that entrance of water into the compartment can be readily controlled.

A pump 12 of any suitable type is operatively connected as at 13 to a motor 14 for draining the compartment and to facilitate the circulation of water through the compartment. It is to be understood that the motor may be of any desired make and positioned at any convenient point on the vessel. The pump 12 has connected thereto a suction pipe 15 which extends downwardly into the compartment and ends short of the bottom 5 of the vessel. An outlet pipe 16 is secured to the pump 12 and has its free end bent downwardly as at 17 and extended over the side of the vessel for leading the water from the compartment 3 over the side of the vessel.

Suitable crates 18 are provided in which the lobsters are adapted to be packed and the crates are provided with openings '19, whereby the entrance of water through the same may be readily had. formed on each end wall of said crates to facilitate the easy handling thereof.

In operation of the improved device, the lobsters are packed in the compartment 3 and at the desired time the valves are opened so as to allow the entrance of water into the compartment and the pump 12 is operated so as to' pump the Water from the compartment and thus p'royide a circulation throughthe compartment and provide ,a continuous supply of fresh Water to the lobsters. It has been found by practical experience that lobsters only require water every seven or' eight hours and after the lobsters have been kept in" the. water a predetermined length of time the valves are closed and the pump operated until theco'mpartment is drained. By this" method the vessel can; proceed: to runundei' a comparaever light load at alltimes and it "is not necessary to stopth'e vessel when desired to supply the lobsters with a fresh supply ning under a compartment filled with water and lobsters as the lobsters are often thrown around the compartment until killed.

In practice, I ha, e found that the form of my in'iei'iti'on illustrated in the accompanying drawings and referred to in the above description, as the preferred ehibbdiment, is the most efficient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary; I desire to emphasize that various minor changes. in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as" set forth.

' What I claim as new is: c c 7 Alcommercial boat of the class described having: a pair of spaced partitions therein defining a central water tight compartment,

pipes connecting the, compartment with the sea-,1 Valves controlling the flow of water through the pipes, means for operating the valvesfrom the deck of the vessel, a pump for draining the water from the compartment, means for operating the pump, said pump, pipes and valves forming means for filling the compartment with Water toa point above the seal'evel or Waterline of boat when so desired, by reversing suction and discharge of pump and letting water run out through pipes instead of in through the same-for circulation.

Intestimony whereof I afiix my signature.
